Elasticsearch version 8.0.0-beta1
Also see Breaking changes in 8.0.
Known issues
-
If you’re using machine learning, it’s not safe to upgrade to
8.0.0-beta1
if the cluster you’re upgrading was first used prior to 7.7.0.
If you attempt such an upgrade the filtered aliases against
the machine learning results indices will lose their filters, causing machine learning
anomaly detection results for different jobs to be mixed.
Wait for 8.0.0-rc1 before attempting to test upgrading a cluster
where machine learning was used prior to version 7.7.0.
-
System indices are included in wildcard queries when using the
* pattern. Do
not rely on this behavior, because system indices will be hidden in the 8.0
release. If you need to access system indices, specify the index name, use a
more specific wildcard, or use the expand_wildcards parameter in your query.
-
By default, system indices are included in snapshots of all indices, and are
restored when no indices are specified. This behavior results from including
system indices in the implicit default wildcard (
*) for snapshot and restore
operations, which was intended for backwards compatibility in 7.x versions.
In 8.0, all system indices should be accessed through the feature_states
parameter of the snapshot or restore request.
